Passage of time v3.0 with PWM

I added PWM to the fifth iteration of my Passage of Time project. The switches still work as in the previous version – the rocker switch for on/off, the toggle for switching patterns and the pushbutton to add in a third pattern. The PWM support only 6 of the 12 LED’s in the time piece and the second pattern augments the fade in/out with additional non PWM LED’s.
